# Usage instruction:
#
# 1. Download it on your NN in any folder.
# 2. Edit rpc username and pass in script.
# 3. Let's explain we have 450 KMD on balance, including 0.0001 KMD utxos.
# 4. Run the script ... it locks all 0.0001 KMD utxos from sending and shows you locked utxos txid + vout num.
# 5. Send funds from NN via ~/komodo/src/komodo-cli sendtoaddress YOUR_WALLET_ADDRESS 450 "" "" true
# 6. Now we need to unlock (!) 0.0001 KMD utxos, uncomment last line with curl command execution and launch it again. All your utxos will be unlocked.
# 7. Additionally check that you haven't locked utxos: ~/komodo/src/komodo-cli listlockunspent
# ...
# 777. Bingo! )
#
# @kolo You can call it "utxo protector", komodod will never "eat" your utxos during sendtoaddress if they are all locked.
